По п. 6. Всю переписку нет смысла транслировать - в ней мои сплошные незнания данного протокола. Ретранслирую только часть )
я ----------------------------------------------------------- Dear Support. There is a next information in documentation for KNX/ModBus Slave gateway: 1440 bytes for read and 1440 bytes for write. So I have about 25 KNX devices with approximately 50 KNX points at every KNX device. So.. how much gateways i must to use for convert all KNX points to modBus tcp registers?
сапорт ------------------------------------------------------------ -Do you need just to read or write too these data points? -Which is the data format of these data points? Bit, words, Float? ------------------------------------------------------------- я -------------------------------------------------------------- 1) This is AHU units with Siemens synco KNX controllers 2) I don't know how much points can provide every controller, approx: 20 points for read (temperatures, humudities, pressures ect) - i think types is float 10 points for write (temperature setpoints,humidity setpoints ect) - i think types is float (but this points also must be reading) 10 points for read statuses - i think types is word Also there are some bits for read/write (for example General Start, feedback from ventilators ect) So I think, 50 points (float) for every KNX controller of AHU system is enough -------------------------------------------------------------- сапорт -------------------------------------------------------------- usually, on KNX side, Float values are Float16 (word). This is a particular format used on KNX.
In this case, you will have a total of 100 words (200 bytes) for each KNX device to read and 20 words (40 bytes) for each KNX device to write. About the requests, you will have 50 points to be read and 10 to be written. --------------------------------------------------------------
То есть если я правильно понимаю, то хотя бы только на чтение получается 200 байт /на один контроллер и соответственно 1400 байт/на 7 контроллеров - то есть в моем случае один шлюз потянет приблизительно 7 контроллеров (всего лишь) ?
